CNN presidential debate moderator Jake Tapper’s show is at the center of a defamation suit brought by a consulting company which alleges that the network and one of its reporters lied about the company’s work.

The network’s defense: CNN did not intend to harm and its language was “opinion or ambiguous.”

Tapper is set to co-host the first presidential debate next Thursday which is being hosted by his network. The host has come under scrutiny from former President Donald Trump, who is set to participate in the debate, for his partiality— calling him “Fake [Jake] Tapper.”

But, as the well-known CNN personality gears up for that debate he also finds himself in the middle of a lawsuit against his employer by security consulting firm Nemex Enterprises and its owner Zachary Taylor, who worked to help evacuate Afghanis following the chaotic Taliban takeover of that country.
